TECHNICAL FIELD

[0002] The present invention relates to sliders for reclosable bags, and more particularly, to holding devices for sliders.

BACKGROUND ART

[0003] The use of reclosable bags for the storage of items is well known. Such bags are used to store a variety of articles, from food to general household items including everything from work supplies to children's toys. Often, such bags include a closure device or mechanism in the form of mating male and female closure elements that are occluded over a width of the bag in order to close the bag. This can be a problem for many people with large fingers or people with manual dexterity problems. In the past, this problem has been solved by adding a slider on the closure device, wherein the slider can be moved along the width of the bag to open and close the bag. For some individuals, a slider does not have a large enough gripping area, and hence, the user may still have difficulty in opening and closing the bag.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] The holding device 20 of the present invention is adapted for use with a reclosable bag 22 with slider 24 as seen in FIG. 1. The reclosable bag 22 includes first and second body panel portions 26, 28 joined together to form first and second bag walls 30, 32. The first and second bag walls 30, 32 are joined at first and second side portions 34, 36, respectively, and at a bottom portion 38. An opening 40 and a closure mechanism 42 are disposed at a top portion 44 of the bag 22, wherein the slider 24 is positioned over the closure mechanism 42 and can be moved along a width of the bag 22 to open and close the closure mechanism 42. The closure mechanism 42 may be in the form of a thermoplastic zipper.

[0031] Now referring to FIGS. 2 and 3, a first embodiment of the holding device 20 of the present invention includes a base surface 52 and two resilient holding members 54 a, 54 b parallel to one another and extending from and perpendicular to the base surface 52. The holding device 20 further includes a channel 56 extending fully therethrough wherein the channel 56 has a width W1 greater than a thickness of the closure mechanism 42. A chamber 58 is located in a center 60 of the holding device 20. The chamber 58 extends along a majority of a length of the channel 56, but ends slightly before a first end 61 and a second end 62 of the holding device 20. The chamber 58 also has a width W2 larger than the width W1 of the channel 56. The chamber 58 is in the shape of a slider and is slightly larger than the slider to which the holding device 20 may be engaged.

[0032] Optionally, in any of the embodiments disclosed herein, a magnet 64 may be attached to an outer surface 66 of one or both of the holding members 54 a, 54 b as seen in FIGS. 3 and 7, or to an outer surface of the base surface 52 as seen in FIG. 4, preferably an outer surface 66 that is relatively flat. Whether or not the holding device 20 is engaged with a slider 24 of a reclosable bag 22, the magnet 64 attached to the holding device 20 can be secured to a magnetic surface to suspend the reclosable bag 22 therefrom. Other miscellaneous items such as papers or coupons can also be held under the magnet 64. Other attachment means can be used to secure the holding device 20 to a wall or other surface including a hook and loop fastener (commonly referred to as a Velcro™ fastener) (FIG. 9), an adhesive, double-sided adhesive tape (FIG. 5), one or more screws or nails, a hook, or the like.

[0033] The holding device 20 of FIGS. 2 and 3 is insertable over the slider 24 in a first direction by pulling the holding members 54 a, 54 b outwardly in opposite directions perpendicular to the holding members 54 a, 54 b, sliding the holding device 20 over the slider 24, and allowing the holding device 20 to return to its original shape. One or both of the holding members 54 a, 54 b may include an inwardly-directed tab 67 a or 67 b that is disposed in interfering relationship with one or more portions 69 a and 69 b of the slider 24 when the holding device 20 is in the undeformed state. Further, the holding device 20 can be removed from a slider 24 by performing the same steps and sliding the holding device 20 off of the slider 24 instead of onto the slider 24.

[0034] One or more grasping members 68 a, 68 b as seen in FIG. 4 may also be provided on a bottom portion 70 of one or both of the holding members 54 a, 54 b that facilitate grasping by a user so that the user can easily move the holding members 54 a, 54 b away from one another. Optionally, a notch or undercut portion 74 as seen in FIG. 5 may be formed in the bottom portion 70 of one or both the holding members 54 a, 54 b. The notch 74 offers a place for a user to grip the holding device 20 with a finger or fingernail in order to pull the holding members 54 a, 54 b away from one another.

[0035] Once the holding device 20 is attached to the slider 24, a user may use the holding device 20 to facilitate the opening and closing of the closure mechanism 42 of the bag 22. This is done by gripping both the holding device 20 and bag 22 and moving the holding device 20 relative to the bag 22.

[0036] In another embodiment of the holding device 20 as seen in FIGS. 6 and 7, the holding members 54 a, 54 b are hinged together at a center 77 of the base surface 52 and a coil spring 78 biases the holding members 54 a, 54 b toward the positions shown in FIG. 7. The holding members 54 a, 54 b may include first and second clip members 80 and 82, respectively. When a user squeezes the first and second clip members 80, 82 toward one another, bottom portions 83 a and 83 b of the holding members 54 a, 54 b, respectively, move away from one another, thus increasing the distance between the bottom portions 83 a and 83 b. At this point, the user may place the holding device 20 over the slider 24 and the clip members 80, 82 may be released, thereby causing the bottom portions 83 a and 83 b to move toward one another under the force of the spring 78 to capture the slider 24 therebetween. The holding device 20 is removed from the slider 24 by squeezing the clip members 80 and 82 together, thereby moving the holding members 54 a, 54 b out of interfering relationship with the slider 24 so that the holding device 20 can be removed therefrom.

[0037] Regardless of the embodiment, the holding device 20 can have various shapes and sizes. For example, the holding device 20 can be in the shape of a child's toy, such as a toy truck as seen in FIGS. 8 and 9. The holding device 20 of this embodiment is similar to those of FIG. 2 and 3, except that the base surface 52 and holding members 54 a, 54 b form the shape of the truck. The holding device 20 can take the shape of other objects, such as a toy train, car, truck, plane, doll, crayon, or cartoon characters. Other shapes can include a flower, different types of animals and insects (e.g., a ladybug), a gift as seen in FIG. 10, holiday decorations (an example of which can be seen in FIG. 11), food items, or sports items such as a baseball, a basketball (FIG. 12), or a football (FIG. 13).

[0038]FIG. 14 shows a reclosable bag 22 having a holding device 20 in the shape of a truck engaged with a slider (not seen) of the bag. Once engaged with the slider, the holding device 20 is grasped by a user and is moved from the side portion 34 to the side portion 36 and back to the side portion 34 to open and close the bag 22.

[0039]FIGS. 15-17 illustrate a further embodiment of the present invention. The holding device 20 is similar to that of FIGS. 8 and 9 with a few exceptions. First of all, a chamber 58 extends along the majority of a length of the channel 56, but ends slightly before a first end 61 and continues fully through to a second end 62 of the holding device 20. The holding device 20 of FIGS. 15-17 includes a flange member 90 extending from the base surface 52 near a top of the channel 56. A clip member 92 is disposed at an end 94 of the flange member 90 to facilitate manual grasping and movement of the flange member 90 toward and away from the base member 52. As seen in FIG. 17, a tab 96 extends from a bottom surface 98 of the flange member 90, wherein the tab 96 is positionable in interfering relationship with a portion of the slider as noted in greater detail hereinafter to prevent movement of the slider out of the holding device 20.

[0040] In order to insert the holding device 20 of FIGS. 15-17 over a slider, a user initially positions the holding device over the closure mechanism 42 such that the second end 62 is disposed adjacent the slider 24. The user then moves the tab 96 upwardly and slides the second end 62 of the holding device 20 over the slider 24 until the slider 24 is fully inserted into the chamber 58. The user may then release the tab 96 whereupon the tab 96 returns to its original position and provides an interference with the slider 24 to retain the holding device 20 on the slider 24. To remove the holding device 20 from the slider 24, a user must lift the clip member 92 and tab 96 upwardly, thus eliminating the interference, thereby allowing the user to move and thereby remove the device 20 from the slider 24.

[0041] Further embodiments of the present invention are shown in FIGS. 18 and 19 and include a handle 100 that swivels from a pivot point 102 and which is attached in any suitable fashion to the holding members 54 a, 54 b of the holding device 20. The handle 100 allows a user to grasp the handle 100 and pull the handle 100 in an opening or closing direction. The swiveling handle 100 can be added to any of the embodiments of the present invention. Also, the handle 100 may be formed into or include at a top portion 106 thereof any ornament 104, such as a pet as seen in FIG. 19, or any desired shape, for example, as suggested above.

[0042] The holding device 20 of the present invention is preferably made of a plastic material such as nylon, polystyrene, polypropylene, Delrin®, ABS copolymer, polyester, mylar™, polyurethane, PVC, polyethylene, and vinyl. The holding device 20 can also be made of metals such as stainless steel and aluminum and foam materials such as urethane foam, polyethylene foam, polypropylene foam, styrofoam, and Volara™ foam.
